Rosen Aviation 1. INTRODUCTION The Headphone Distribution Amplifier 0700-001 features three audio inputs, a pilot mic input, and eight controllable audio outputs. The pilot mic input will override the other inputs when active. The unit is designed to integrate into any entertainment system with analog audio capability and controllers that allow you to select different audio sources in the aircraft.

Rosen Aviation 2.1. Operating Modes Each output channel may be configured to one of two modes of operation by setting the DIP switches according to the ON indicators on the audio distribution amplifier. Fixed output Keeps the output channel set to a specific input channel: either A, B, or C. Switched output Allows the user to select input channels independently of the other output channels. Requires a source select switch wired to the unit. 3.

Rosen Aviation 4. CONFIGURING A SINGLE OUTPUT CHANNEL Configuring a single output channel depends on several variables. Number of audio inputs Use of a source select switch (such as a controller, IR remote, or at the seat) Choice of fixed inputs: channel A, B, or C 4.1. Fixed Mode Example If you are using only one input, you do not need a source select switch or need to enable channel C. If you do not need a source select switch for the output channel, see Table 1.
PAGE 7
Rosen Aviation To configure the remaining output channels (2-8), copy the appropriate switch settings from Tables 1-3. Fixed modes will use either an ON/OFF, OFF/ON, or OFF/OFF combination and switched modes will always use the OFF/OFF combination. If you use three audio sources and a source select switch, configure the DIP switches as shown in Table 3. The Channel C Enable switch must be ON to use the third audio input.

Rosen Aviation 5. MOUNTING Mount the Headphone Distribution Amplifier in any orientation using the four mounting slots in the flange brackets on the exterior housing. Refer to Note 3 on the Outline and Installation Drawing 0700-001-CD. 6. ADJUSTING THE MAXIMUM AUDIO LEVEL The factory defaults for the potentiometers, as shown in Figure 4, are set to line level. This means that the signal coming out of the amplifier is equal to the signal going in.
